A strategically placed binder clip or a chunk of cinderblock are both cheap and easy ways to stop unused nuisance cables from falling off your desk. But why settle for those eyesores when the MOS, or Magnetic Organization System, provides a far more elegant way to tether all your wires?

It's basically a contoured triangular magnetic monolith that will securely hold your cables when not needed, and easily release them when you do. The underside features a non-slip surface so the MOS itself will always stay perched on your desk, and the $20 starter kit includes three magnetic straps should you find a cable that's not attracted to its invisible magnetic charms.
